A study of poultry waste management and utilization techniques in urban vegetable farms in metropolitan Lagos revealed that poultry waste is poorly collected, packaged, and transported. Proper knowledge on treatment is lacking due to insufficient skill, space, time, and capital. Furthermore, a significant difference was found between poultry waste utilization, crop yield, and revenue in the study area.

A study interviewed 202 urban vegetable farmers in four areas of Lagos, Nigeria, to understand urban farming operations and contributions. Farmers typically owned linear plots under 120m by 60m, primarily growing green vegetables (Celosia argientes) and using local tools, chemical fertilizers, and irrigation wells. They used produce for household consumption, sold to local marketers, and helped stabilize vegetable prices.

A study of resource use and productivity among 70 urban farmers drawn from the two main cultivator groups—Fadama and Okiti—in Ilorin, Kwara State, Nigeria, using focus group discussion, non-participant observation, and a questionnaire survey. Multiple regression analysis identified pump-machine use, vegetable-plot harvest, use of modern inputs, and labor type as determinants of efficiency, together accounting for 89.6% of the contribution to land use, the main resource. Fadama cultivators operated at a larger scale with correspondingly higher profit than Okiti cultivators, and although both groups faced similar environmental and input-access constraints, the two systems differed fundamentally in scale and production efficiency.

Soil and vegetable samples (spinach, jute mallow, and tomato) were collected from farms and gardens across 20 zones within Kaduna, Nigeria, plus two rural control villages about 30 km from the city, and analyzed for heavy metals by Flame Atomic Absorption Spectrophotometer. Pollution Load Index results showed soils in the city farms were moderately enriched with cadmium and chromium and strongly enriched with lead and nickel from anthropogenic sources. Mean soil concentrations of lead and cadmium exceeded WHO/FAO permissive limits for agricultural soil (nickel and chromium did not), while vegetable metal concentrations exceeded the permissive limits for every metal except nickel — a finding flagged as concerning given the toxicity of lead and cadmium in particular, which have no known biological use.

A study of Enugu Urban, Nigeria, examining farmers' perceptions of the health and environmental hazards posed by keeping livestock in urban areas, and the implications for climate change mitigation. Seventy-five heads of household were freely sampled and interviewed, with data analyzed using percentages and means. Most farmers kept improved chicken breeds under an intensive system. All respondents were aware of health and environmental implications of urban livestock keeping, but only 4.0% were aware that livestock could contribute to climate change. Reported environmental issues included crop destruction (89.3%), filth in urban areas (89.3%) and noise (88.0%); health issues included disease spreading (50.7%), accidents (46.7%) and bad smell (86.7%). Perceived control measures included proper waste disposal (mean 1.79), seeking veterinary services (mean 1.85), regular shed cleaning (mean 1.80) and provision of extension services (mean 1.85). The study recommends integrating urban agriculture into urban health and environmental policy and having extension services raise awareness of livestock's climate impact among urban keepers.

A thesis examining peri-urban agriculture in Asmara, Eritrea, within an analytical framework of urban population growth encompassing natural population increase, rural-urban migration, and outward movement linked to urban expansion. It draws on primary field data collected with research assistants, secondary data from Ministry of Agriculture and Ministry of Public Works reports, and focus group discussions. Respondents in the context of natural population growth were found to make a viable living from peri-urban agriculture, but also to face considerable challenges. Three sub-groups of farmers were identified; poultry farmers were the most vulnerable, owing to high input costs, uncertainty from avian flu, and an undeveloped distribution network. Vegetable producers had a sophisticated marketing network but low levels of education, large households, and an impending shortage of land and water. The abstract's description of agriculturalists who migrated to Asmara is cut off before stating a conclusion.

Enow Ajebe, Anna Granberg · · Sub-Saharan Africa

A study using qualitative data from 24 urban farming households in Kumba municipality, Cameroon, drawing on key informant interviews with the government agriculture delegate and questionnaires administered to farmers. Urban agriculture was found to have become an important source of fresh produce, employment, and income for those practicing it, but this activity and the livelihoods depending on it were found to be threatened by a number of problems. The study also finds that while urban agriculture contributes to household food supply, its magnitude in terms of utilization, availability, dietary diversity, and financial contribution should not be overemphasized. Suggestions are offered for improving the sector.

This study examines the motivations behind women's involvement in urban agriculture in small agro-towns of Kwara State, Nigeria. A total of 1,801 women farmers were selected from 13 settlements across 8 local government areas, and data were analyzed using simple percentages, graphic illustrations, charts, cross-tabulation, and stepwise multiple regression. The study identifies three factors — food security, income supplement, and accessibility to land — as the best predictors of women's involvement, together accounting for 98.6% of the explained variation. It recommends official recognition of urban agriculture and provision of financial resources to help women expand their farm plots.

This study examines the impact of school garden programmes on nutrition knowledge and food security among primary school students in rural Mozambique. While such programmes have been implemented across various regions with mixed results, this study used a mixed-methods approach combining qualitative interviews and quantitative surveys with primary school students and their parents or guardians. Students showed a statistically significant improvement (p<0.05) in nutrition knowledge, with an average score increase of 20% on the post-intervention survey compared with pre-test results. The findings indicate that the school garden programmes positively influenced students' nutritional knowledge and contributed to their families' food security in Mozambique's rural areas. The authors state that further studies should examine long-term impacts and potential barriers to implementation.

This article examines the contemporary importance of household food production in poor urban communities across 11 Southern African Development Community (SADC) cities. It finds that urban food production is not particularly significant in most communities, with many more households relying on supermarkets and the informal sector for food access. Furthermore, few households derive income from selling produce, though the situation varies considerably by city.

A book chapter surveying the state of urban agriculture in African cities. As rural-to-urban migration increases demand for food quantity and quality, urban agriculture is described as able to contribute to livelihoods and economic growth; horticulture is called a vital economic sector, citing figures such as Côte d'Ivoire's fruit and vegetable exports to the EU exceeding 360,000 tons, Burkina Faso's 2007 green bean exports of over 925,000 tons, and Mali's tomato and okra production reaching over 17,000 tons and 8,600 tons respectively. The chapter also notes that the horticultural sector, including urban agriculture, faces pest attacks and phytosanitary problems and must comply with pesticide regulations and quality-control (traceability) standards required by export markets.

This paper examines rural-urban migration's impact on agricultural and national development in Nigeria and argues that extension policy has focused primarily on rural agriculture, neglecting urban agriculture's role in poverty alleviation. It recommends that extension agencies organize urban-specific extension services to inform smallholder urban farmers about which food products are in demand in urban areas, without presenting original survey or experimental data.

This qualitative study assesses the Mogabane Community Garden Project in South Africa to determine why it did not reach its objective of poverty reduction in the community. It situates the project against South Africa's poverty lines — roughly 33% of the population living on less than R271/month, 50% on less than R422/month, and 79.1% on less than R1,230/month, with the highest poverty rates in the Eastern Cape (68.3%) and Limpopo (60.7%) provinces and the lowest in the Western Cape (20%) and Gauteng (28.8%) — and the government's post-1994 anti-poverty programs spanning social assistance, employment generation, enterprise development, basic household security, social services, disaster relief, and employment-related social insurance. Against this backdrop, the study assessed the Mogabane project and confirmed that it failed to achieve its poverty-reduction objective.
